Banking Journeys / Implementation Paths

From first workflow to full platform.

Adopt CoreFi at the speed your bank, your regulator and your customers can absorb. Five paths — Launch New, Modernize One Journey, Run Alongside Legacy, Migrate Progressively, or Operate as a Managed Platform. Same platform, same audit trail, different on-ramps.

Explore AI Workflows

Why it matters

Adopting AI banking shouldn't require a re-platforming bet.

Most "next-generation core" projects fail the same way: a single, multi-year, all-or-nothing migration that the executive team cannot reverse without writing off the budget and the brand. CoreFi is built so that does not have to be the choice you make.

Whether you are a fintech going to market for the first time, a bank modernizing one journey at a time, or an institution committed to retiring a legacy core over several years, the platform underneath stays the same — a real-time core ledger, headless APIs, governed AI workflows, and a single audit record. Only the on-ramp changes.

Each of the five paths below is one CoreFi is built to deliver. Each names who it fits, how long the first phase takes, how it integrates with what you already run, what "done" looks like, and how you exit if your strategy changes. Pick one to start, change later — the platform is designed for that.

The five adoption paths

Five ways to put CoreFi into production.

Each path uses the same platform — core ledger, headless APIs, governed AI workflows, audit trail. What differs is what CoreFi replaces, what it sits next to, and how fast.

Launch New

Greenfield digital bank, neobank, fintech, EMI or BaaS programme.

Who it's for: Founders, programme leads and sponsoring incumbents launching a banking proposition from scratch — and who need to be live in months, not years.
Typical timeline: First production customer in 12–20 weeks; full retail or SME proposition (deposits, cards, lending, channels) inside two quarters.
Integration approach: CoreFi is the system of record from day one. Onboarding, ledger, lending, payments and the AI workflow control plane all run on CoreFi APIs. Channels (mobile, web, partner) connect via Headless APIs or White-Label.
Success criteria: Licence-ready architecture validated by your auditor; first cohort of production customers onboarded; daily settlement and reconciliation running inside CoreFi; AI agents handling onboarding and service triage with human-approval gates active.
Exit / lock-in posture: Customer, account, ledger and audit data exportable through documented APIs; standard double-entry ledger model; no proprietary data formats. Switch the platform off and you keep the records.
Sample CTA: Plan a greenfield launch.

Modernize One Journey

Replace one product line on a legacy bank without touching the rest.

Who it's for: Established banks and lenders that want to ship a new product — SME lending, savings, instant onboarding, embedded credit — without re-platforming. Programme heads, digital product owners and chief digital officers.
Typical timeline: 8–14 weeks to first customer for a single journey (onboarding, lending application, deposit product or service workflow).
Integration approach: CoreFi runs the new journey end-to-end on its own APIs and pushes the resulting accounts, balances or postings back into the legacy core in near real time or on a nightly batch. The legacy core stays the system of record for everything else.
Success criteria: One full journey live in production; accuracy and speed metrics versus the legacy equivalent reported to the steering committee; AI agents handling at least one bottleneck step (credit memo prep, KYC exception triage) under human approval.
Exit / lock-in posture: The journey is decoupled from the rest of the bank by design. If you decide to retire it, the customer file and the audit trail come back to your core through the same connectors used during sync.
Sample CTA: Pick a first journey.

Run Alongside Legacy

A second core for a discrete segment, in parallel with what you already operate.

Who it's for: Banks and financial institutions that need a second core for a defined segment — digital-only customers, SME, a new geography, a new product portfolio — alongside the existing core. CIOs, CTOs and chief operating officers running multi-brand or multi-country operations.
Typical timeline: 16–24 weeks to first segment live on the parallel core; ongoing dual operation for as long as the business case requires.
Integration approach: CoreFi runs as a fully independent core for the chosen segment, with two-way data flows to the legacy core for shared functions (general ledger consolidation, regulatory reporting, treasury, customer master where required). No customer migration is forced.
Success criteria: The new segment runs entirely on CoreFi without disrupting the legacy book; consolidated regulatory reporting reconciles cleanly across both cores; AI workflows deliver a measurable cost-to-serve advantage on the new segment.
Exit / lock-in posture: The two cores remain operationally independent. Unwinding the parallel core means switching off connectors and exporting the segment — not a re-platforming project on the rest of the bank.
Sample CTA: Scope a parallel core.

Migrate Progressively

Phased core swap, never a single big-bang cutover.

Who it's for: Banks committed to retiring a legacy core but unwilling to bet the institution on a single big-bang migration. CIOs, CFOs and programme directors with board-level sponsorship and a multi-year budget.
Typical timeline: 18–36 months end-to-end, broken into product- or segment-shaped phases that each go live in 3–6 month increments.
Integration approach: Strangler pattern — each customer cohort, product line or geography migrates to CoreFi on a defined cutover. CoreFi and the legacy core coexist for the duration, with CoreFi taking over each domain as it migrates. AI workflows are introduced phase by phase, never as part of a cutover.
Success criteria: A signed migration sequence with measurable per-phase exit criteria; zero customer-facing downtime per cutover; the legacy core fully decommissioned by the end of the programme with audit-ready evidence.
Exit / lock-in posture: Each phase is independently reversible until cutover. Data from migrated phases is exportable on the same terms as Launch New. The bank keeps the right to halt or re-sequence the programme between phases.
Sample CTA: Map your migration phases.

Managed Platform

CoreFi-operated platform; you keep the customer, the brand and the licence.

Who it's for: Programme owners that need a banking proposition live without standing up an internal core-banking and AI-operations team — embedded-finance programmes, fintech ventures inside larger groups, asset managers issuing tokenized products, and banks running an experimental segment.
Typical timeline: 10–16 weeks to first customer; ongoing operations handed to CoreFi under a managed service contract with defined SLAs.
Integration approach: CoreFi runs the platform on your behalf — infrastructure, releases, monitoring, AI workflow tuning and second-line operations — while you keep the customer relationship, the brand and the regulatory permissions. You consume the platform through APIs, white-label channels and an operations console.
Success criteria: Service-level commitments met every month (uptime, response time, regulatory deadlines); AI workflow performance reported against agreed business KPIs; clean separation between CoreFi-managed operations and the activities that must remain inside your regulated entity.
Exit / lock-in posture: Managed service contracts include a defined off-boarding path — code, data, audit trails and AI workflow definitions transfer to you or another operator within agreed windows.
Sample CTA: Outsource the operating model.

Implementation building blocks

Seven steps under every path.

The on-ramp differs; the work underneath does not. Every CoreFi deployment moves through the same governed sequence — so what you learn on one journey is reusable across the rest of the platform.

Discovery & target architecture

One to three weeks. We map current systems, regulatory boundaries, data residency, AI policy and the journeys you intend to ship. The output is a target architecture and a phased plan, signed by your team and ours before any environment is built.

Sandbox & API access

Week one. Engineering, risk and compliance get hands-on access to a sandbox tenant, the Developer Center, sample data and the AI workflow templates relevant to your path. Integration spikes start in parallel with the architecture work.

Identity, permissioning & policy gates

Roles, scoped API tokens, transaction limits, customer-segment rules, jurisdictional restrictions and human-approval thresholds are configured before anything goes live. The agent literally cannot call an API it has not been granted.

AI workflow control plane

Onboarding, lending, treasury, compliance and service workflows are wired to the journeys in scope. Each agent runs through the seven-step lifecycle (Sense → Plan → Check → Act → Audit → Escalate → Learn). Approval gates are owned by the bank.

Pilot, parallel run or phase cutover

Depending on the path, we run a pilot cohort, a parallel-core operation, or a phase cutover. Outcomes are compared to the legacy or expected baseline. Nothing widens until the metrics agreed in step 1 are met.

Go-live

The first customer cohort or segment moves to production. Reviewer dashboards, audit logs, regulatory reporting and incident runbooks are operational. CoreFi support shadows your operations through the first reporting cycle.

Operate, govern, audit

Steady-state operations: AI workflow performance, exception rates, override rates, audit exports and regulatory submissions reviewed on a monthly cadence with your team. Each next phase or new journey reuses the same control plane.

Choose a path

Which adoption path fits your situation.

A short decision aid. None of these is binding — most banks combine two over time (e.g. start with Modernize One Journey, graduate to Migrate Progressively).

You don't have a banking platform yet.

Start with Launch New. Greenfield is the shortest path to a regulated proposition; CoreFi is your system of record from week one and you avoid carrying integration debt you would otherwise have to undo.

You have a legacy core and want one new product live this year.

Start with Modernize One Journey. CoreFi handles the new product end-to-end and writes back to the legacy core. No re-platforming, no board-level migration programme.

You need to run a separate segment, brand or geography in parallel.

Start with Run Alongside Legacy. Two cores, one bank — CoreFi handles the new segment, the legacy core handles the rest, regulatory reporting consolidates across both.

You have a board mandate to retire the legacy core.

Start with Migrate Progressively. The strangler pattern moves customers, products or geographies in 3–6 month phases, each independently reversible until cutover. No big-bang.

You don't want to operate the platform yourself.

Start with Managed Platform. CoreFi runs the platform under SLA; you keep the customer, the brand and the regulated activity inside your entity.

FAQ

Six questions buyers ask first.

Can we change paths mid-flight?

Yes. The platform is the same in all five cases — only the on-ramp differs. The most common move is starting with Modernize One Journey or Run Alongside Legacy and graduating to Migrate Progressively once the bank has confidence in the platform.

Are AI workflows available on every path?

Yes. The AI workflow control plane is part of the platform in every deployment. What differs is which journeys are in scope at go-live; new journeys can be added later without re-architecting the bank.

How do you handle our existing core during a parallel run or phased migration?

CoreFi connects to the legacy core through APIs and event streams. We do not require a particular legacy vendor; we have run alongside mainframe-era cores, modern providers and home-grown systems. Reconciliation and consolidated reporting are designed in from day one.

What does the regulator see?

One audit record per workflow — trigger, retrieved data, model and prompt version, plan, policy outcome, API calls, ledger effects, escalations, human decisions, final state. Exportable for internal review, external audit and supervisory requests.

Who owns the data?

You do, on every path. Customer, account, ledger and audit data are exportable through documented APIs in standard formats. The Managed Platform contract adds an explicit off-boarding path so the data, code and AI workflow definitions can transfer to you or another operator.

How do we price this?

Pricing tracks the path. Launch New and Modernize One Journey are usage-based on accounts and workflows. Run Alongside Legacy and Migrate Progressively add a programme fee for the parallel-operation period. Managed Platform is an SLA-backed service contract. We will scope it with you on the first call.
